Manufacturing method of glass substrate for magnetic disk and manufacturing method of magnetic disk |
| abstract |
PROBLEM TO BE SOLVED: To prevent the occurrence of a thermal asperity failure or a head crash failure even when flying a magnetic head with an extremely narrow flying height of 10 nm or less, and to prevent a recording / reproduction failure (error). A method for producing a glass substrate and the like are provided. In a method of manufacturing a glass substrate for a magnetic disk including a chemical strengthening step for strengthening a glass substrate by bringing the glass substrate held by a holding means into contact with the chemical strengthening treatment liquid, the chemical strengthening treatment liquid is stored. The holding means for holding at least the wall surface and / or the glass substrate in contact with the treatment liquid of the chemical strengthening treatment tank is made of a metal material (for example, NiCrMo alloy) mainly composed of Ni having corrosion resistance against the chemically strengthened molten salt. Constitute. [Selection figure] None |
